Kata OBS to Packagecloud sync tool

• How it works
• Detailed behaviour
• Install and Usage

kata-pkgsync is a tool to synchronize Kata package from OBS to Packagecloud.

How it works

kata-pkgsync autonomously discovers OBS packages, repositories, and architectures in a OBS project. It can detect:

• which of the binary files published on OBS are already stored on Packagecloud,
• which ones still needs to be synchronized,
• which packages on Packagecloud are orphans, i.e. do not have a corresponding file published on OBS.

Based on this information, kata-pkgsyncs can download only the necessary files from OBS, upload them on Packagecloud, and delete orphans Packagecloud packages.

Detailed behaviour

This is the sequence of tasks executed:

1. Fetch the configuration from a YAML config file.
2. For each OBS project specified, retrieve the available repositories, architectures, packages. For each combination of {repository,architecture,package}, retrieve the list of the build artifacts (i.e. the "rpm" / "deb" package files).
3. Get the list of files/packages already uploaded on Packagecloud. This is to avoid re-uploading packages already sent to Packagecloud.
4. Build a list of files that needs to be synchronized from OBS to Packagecloud, and identify which of the Packagecloud files have a corresponding file published on OBS.
5. Download the identified files from OBS. The download phase create a local cache of packages, to avoid re-downloading files if already done.
6. Upload the identified files to Packagecloud.
7. Optionally, delete orphans files from Packagecloud.
